    • Regulation of Fe absorption by cultured intestinal epithelia (Caco-2) cell monolayers with varied Fe status 
      Tapia, Victoria; Arredondo, Miguel; Núñez González, Marco (1996)
      Body Fe homeostasis is maintained through the regulation of Fe absorption by the intestinal epithelia. Working under the hypothesis that the intracellular concentration of Fe is instrumental in the control of its transepithelial ...
    • The cellular mechanisms of body iron homeostasis 
      Nũnez, Marco T.; Garate, Marco A.; Arredondo, Miguel; Tapia, Victoria; Muñoz, Patricia (Society of Biology of Chile, 2000)
      Cells tightly regulate iron levels through the activity of iron regulatory proteins (IRPs) that bind to RNA motifs called iron responsive elements (IREs). When cells become iron-depleted. IRPs bind to IREs present in the ...
